As a general rule when is a micro niche too small? For instance, if google says they receive x number of searches per month for a certain keyword, what is your minimum? And how much is to much competition? For instance, if you google "fish traps" and google shows you have x number of competition for that keyword, how much is too much? I know there are a lot of variables, such as how many back link your competition has etc. But what do you consider a "doable" amount of competition? Thank you
